SPECIFICATION forming part of Letters Patent No. 559,503, dated May 5,1896.

Application nea my 14, 1894.

To @ZZ whom t may concern:

Be it known that l, TIMOTHY J. SULLIVAN, a citizen of the United States,and a resident of the city ot' Albany, in the county of Albany and Stateof New York, have invented certain new and useful Improvements inSiphons for Tanks of Water-Closets, of which the following is aspecification.

My invention relates tosiphons for tanks for containing wate r foriiushing water-closet bowls; and it consists in the combination of partsand devices hereinafter particularly described, and speciiically setforth in the claim.

The objects of my invention are to provide with a short upturned limbconnected with the longlimb of the siphon a horizontal valveseat,reciprocating valve and a valve-cage, whereby the valve will bepreserved from shifting out of place on the valve-seat and the water beallowed to have free passage into the lower end of the long limb of thesiphon for starting the run of water through the entire length of thesame, and also to provide with a guided stem of a vertically-movingvalve and the upper end bend of the siphon a means for holding a leverand a connectin g-rod between the latter and said valve in place,whereby the said lever may at all times be held in one and the samerelation to the said valve. I attain these objects by the meansillustrated in the accompanying drawings, forming a part of thisspecification, in which- Figure lis a plan view of a siphon embodyingthe improvements in this invention. Fig. 2 is an elevation, part insection, of the same. Fig. 3 is a view from above the valve-cage, as atline l in Fig. 2; and Fig. 4 is a side elevation of the said valve-cage.

The same letters of reference refer to similar parts throughout theseveral views.

In the drawings, A represents the siphon, in which a is the short limb,a the long limb, and a2 is an upturned limb connected with the lower endportion of the long limb a and having1 its chamber communicating withthat of said long limb a and also with the outlet d3 of the Siphon.Although this siphon may have its limbs a a a2 and outlet a3 integral,yet it may be made sectional, as shown in Fig. 2, and comprised ot'straight tubes B B',

Serial No. 517,614. (No model.)

return-bend B2, and return-bend B3, having in it the outlet a3, whichoutlet is, through the screw-threaded stem B4, extended from theshoulder b, as shown in Fig. 2. The said tube portions B B are securedwith their respective return-bends B2 and B3 by suitable screw-threads,as shown. end of the upturned limb a2 is provided with a valve-seat c,which is annular to the inletopening O and horizontal as to itsseat-surface.

D is a vertically-moving valve suitably secured to the vertical stem dand the depending guiding-wings d d', which loosely worl; within theinlet-opening O.

F. is an open-work valve-cage suitably sccured to the upper end of theupturned limb a2 and annular to the said valve D. This valve-cage E isprovided with a series of side openings e e and top openings e e,through which water may freely have passage to the outlet-opening O whenthe valve D is raised from off the seat c. A sleeve c2 is providedcentral in the upper end of the said valvecage E, of diametercorresponding with that of the vertical stem d of said valve, so as tofreely Work in the same.

F is a lever-supporting bar secured by any suitable means to the upperend of the Siphon A. This lever-supportin g bar is shown to extend froma boss f, integral with the wall of the bend B2, outwardly to a shortdistance past the vertical shortlimb a and is supported by the said bossand secured thereto by means of the nut-headed screw f', and also bymeans of the laterally-projected lug f2 and hollow stud f3 between saidlug and the said bar and secured by the stem g, integral with the earsG, passing through a perforation made in the outer end of said bar F andthrough the hollow stud fS and the lug f2, as indicated by dotted linesin Fig. 2, when it is secured by the nut g. The ears G receive betweenthem the lever ll, which is pivoted by pivot 7L with the said ears. Oneend of said lever ll terminates at a point about vertically over thevalve D and is connected with the stem d of said valve by means of anysuitable connecting device-as, say, rod itl-while the opposite end ofsaid lever has connected with it suitable means by which the said endmay be pulled down, and which may consist ot` wire or chain 7b2, asshown.

The upper open lOO This siphon is secured in place within the tank I byits screw-threaded stem B4, passing through the bottom I of said tank,with a suitable gasket 'L' between said bottom and the shoulder b. Theflushing-pipe J is secured with said stem B4 by any suitable means, andpreferably by a coupling-collar K, as shown. NVater is supplied to thistank from a supplypipe (not shown) until the water rises to or near tothe water-line w. When this siphon is to be operated, the inner end ofthe lever II is raised by the operator pulling down on the rod or chainh2, when the valve D will be lifted up from the valve-seat c and allowthe water within the cage E to pass at once into the outlet a3, andthence into the i'lushin g-pipe J, to be followed by other water passinginto the said cage through its openings e e, when the water in the tankwill be started to have a flow in direction up through the short limb aof the Siphon, and thence through the long limb a', and then to theoutlet aS to the .ushingpipe J, when the valve D may be allowed to dropdown on its seat and close the inletopening C. The flow of the waterthrough the short and long limbs of the siphon A having been startedwill be continued until the water in the tank has been lowered to withinabout one inch, more or less, from the bottom of the tank.

What I claim, and desire to secure by Letters Patent, is-

In a siphon for tanks for flushing watereloset bowls, the combinationwith the bend B2 provided with the laterally-projected lugfilmer-supporting bar F, secured by one of its ends to the apex of saidbend, and having its Opposite end supported by said lug, of a leverpivoted with ears connected with said bar and Calculated to lift a valvefor starting a flow of water from the tank through the said Siphon,substantially as and for the purposes set forth.
